concern?. v. I I, ERNEST Lf, PERSONS, a citizen "of :the lUnited States, and resident I of` Cook, andState`of have invented certain new and useovercome by the lprocess of embossing and Processes of Embossof which the following is a specification, and which" is illustrated in forming apart 1 wings,

In ornamenting iibrous or leather book covers, signs and the like,

it is common practice to indent the material and stamp foil in the indentations for coloring or ornamenting the same.

This expedient, however, is

the foil is readily detached and even when iirst applied is not as ornamental as is desirable.

differently from l the remaining portions of the material, has heretofore been considered impractical or too expensive to be employed.

vThese diiiiculties and many others #are coloring whichl will :now be described. j

The sheet of material 10 may'comprisea single prepared in the usual manner. J The sheet of on a .straw or'clo'thboard rand ifit is'to be grained or otherwise treated this operation isfperformed afterwhich the -sheet is embossed .'lbyY any suitable mechanism.

In Fig. l the sheet lO is 'shown Vas being in Aa conventional type'V of embosscally. The reference character 11 designates thel head carrying the intaglio plate` and the referencejcharacter'lQ the bed. of the press.

Aftery the sheet 10` has passed through the embossing press as shownin F-ig.`2 of the drawings, the embossed portions are colored Preferably the tional air'brush'l shown more or less diagrammatic'ally,in Figs. 8 and 4.

.The coloring matter is applied on a spot sufiicientlylarge to include the embossed the sheet shown in Fig. 3 contains two [groups of letters 14 and l5 and a bordery design 16 -forming three groups in all. Each group is shown as being in a differently colored spot.

The coloring is preferably done after the embossing because the embossing process stretches, compresses and otherwise distorts the material to such an extent that the coloring would no longer be the embossed surface, if applied before the material is embossed. The coloring matter may be of any suitable composition. Preferably the coloring matter is mixed with lacquer which has been thinned to the proper consistency by a commercial thinnen7 The material is usually mounted smooth and even over sheet offlexible material or a board-'f f covered with asuitable material such as cloth, leather, imitation leather orl other .suitable porous material, 'and is properly lacquer causes the coloring to dry almost immediately, or at least Within a fevv minutes after it has been applied.

The background of the sheet is then given the desired color. This may be accomplished by printing the same. Preferably they intaglio plate or surface of the embossing head is inked and after the sheet is properly positioned so that the embossed characters or design Will registerwith the corresponding depressions in the head the sheet is. printed. In practice, if the border of the sheet contains unembossed portions that are o-f the same color as the embossed portions thereof, the border of the intaglio head is removed before the printing operation. Usually it is made removable but it Ymay be routed out before printing the ground of the sheet. The ground may be printed in any desired color. It may be, and preferably is, of an entirely different color from the coloring of the embossed design as shown at This step. of the process makes the Whole surface of the sheet a single color except the border and the embossed design on the body of the sheet, which remain unaltered.

Any suitable ink may be employed for this printing process. Preferably lithographic ink to Which has been added from 20% to 50% of lacquer, isk employed. The lacquer tends to, hasten the drying of the sheet, but suflioient lacquer cannot be employed for this purpose because it Would dry on the ink'l roll before the inking process could be completed. After the ground has been colored or printed it is necessary to treat the. surface With a drying compound, otherwise the ink will take an indenite time to dry, especially if the sheet of material be of leather.

The surface of the sheet 10 Y is finally treated with a suitable drying compound. Preferably lacquer as thick as; can Well be used is employed for thisl purpose. A coat ofV the drying compound` isv applied, to the Whole surface of the sheet by any suitable means, such as by means of an air brush 13 as shown in Fig. 4L of the drawings.

In order not to modify or change the appearance of the various colors on the sheet,

the drying Compoundv employed is pancia..

The coat of lacquer is not only valuable 17 in Fig. 4t.'

tecting and preservingV the in this relation as a drying agent, but, since it is Waterproof and is not aected by climatic or atmospheric conditions, it will protect the sheet from moisture and Will preserve the freshness of the. colors and appearance of the design for an indefinite length of time.

I claim as my invention:

1. A process of coloring and embossing material, which consists in embossing the material, coloring the embossed portions,

printing the background and treating the Whole With a drying compound.

2. A a-rocess of coloring' and embossing sheets ol' porous material which consists in first embossing said sheets, then suitably coloring the embossed portions, then printingv the background and finally coating the Whole face of the sheet with a pellucid drying and preserving com-pound. Y

3. A process of coloring and embossing sheets of material which consists in embossing said material, coloring the embossed portions, and then inkingk the background. y

4. The process ofr coloring andV embossing porous material which consists inembossing said material, coloring the embossed portions, inking the background and treating the Whole with a coat ofV drying compound.

5.. A she-et of poro-us material provided on its face With a colored embossed design. and a ground of differentl color fromv the design and' a coat of transparent drying material over the Whole face ofl said sheet forl prosame. Y

6. The process oftreating surfaces for ornamentation consisting in embossing the sur-face, coloring the. embossed portions and then treating the unembossed portions with a different color. h

7.. The process: of coloring embossed sheetsl which consists: inV permanently` coloring the embossed portions, of said sheets and thereafter applying a different. color to the. unembossedA portion-s.

8. The process, of coloring'embossedsheets which consists in; applying a. colori1 to. the. embossed portions ofl said sheets, applying a different color to.: the background, and thereafter treating the entire surface of said,

sheet With a drying compound.
